The three main components needed for a wireless Internet connection are a wireless router, wireless network card installed on the computer and an account with a local Internet service provider. Most laptops are shipped with a wireless Internet card. If the user already has DSL or cable access to the Internet, then only the router is needed. There are several types of wireless routers and network cards. A common router brand is Linksys, which costs as low as $59.99.

On the Other: Security Considerations

Wireless Internet connections are less secure than hardwired connections. The data packets are sent over the airwaves, so a malicious hacker can intercept these signals and steal information. It's important for the user to understand the technology and secure the information using encryption. This option is available using the wireless Internet router.

Bottom Line

Wireless access is a convenient way to connect to the Internet. As long as security measures are taken, a wireless Internet access can allow several machines in the home or office to connect without the limitations of wires. However, a wireless connection is typically slower than a hardwired connection.
